CDMA/AMPS 3–4 Volt Power Amplifier (824–849 MHz) - DataSheet

RM912
CDMA/AMPS 3–4 Volt Power Amplifier (824–849 MHz)
The RM912 dual mode Code Division Multiple Access (CDMA)/Advanced Mobile
Phone Service (AMPS) Power Amplifier is a fully matched 6-pin LCC surface mount
module designed for mobile units operating in the 824-849 MHz cellular bandwidth.
This device meets stringent IS95 CDMA linearity requirements to beyond 28 dBm
output power and can be driven to power output levels beyond 31 dBm for high
efficiency FM mode operation. A single GaAs Microwave Monolithic Intergrated
Circuit (MMIC) contains all active circuitry in the module. The MMIC contains
on-board bias circuitry, as well as input and interstage matching circuits. The output
match is realized off-chip within the module package to optimize efficiency and power
performance into a 50 Ω load. This device is manufactured with Conexant’s GaAs HBT
process that provides for all positive voltage DC supply operation while maintaining
high efficiency and good linearity. Primary bias to the RM912 can be supplied directly
from a three cell nickel-cadmium, single cell lithium-ion, or other suitable battery with
output in the 3-4 volt range. Power down is accomplished by setting the voltage on
the low current reference pin to zero volts. No external supply side switch is needed
as typical “off” leakage is a few microamperes with full primary voltage supplied from
the battery.
Distinguishing Features

Electrostatic Discharge Sensitivity
The RM912 is a Class I device. Figure 22 lists the Electrostatic Discharge (ESD) immunity level
for each pin of the RM912 product. The numbers in Figure 22 specify the ESD threshold level for
each pin where the I-V curve between the pin and ground starts to show degradation. The ESD
testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body
Model. Since 2000 volts represents the maximum measurement limit of the test equipment used,
pins marked > 2000 V pass 2000V ESD stress.

Various failure criteria can be utilized when performing ESD testing. Many vendors employ
relaxed ESD failure standards which fail devices only after “the pin fails the electrical specification
limits” or “the pin becomes completely non-functional”. Conexant employs most stringent criteria,
fails devices as soon as the pin begins to show any degradation on a curve tracer.
To avoid ESD damage, latent or visible, it is very important the Class-1 ESD handling precautions
listed in Table 6 be used in the product assembly and test areas follow.
